Mastering Minimal APIs in ASP.NET Core

By: Andrea Tosato, Marco Minerva, Emanuele Bartolesi

Overview of this book

The Minimal APIs feature, introduced in .NET 6, is the answer to code complexity and rising dependencies in creating even the simplest of APIs. Minimal APIs facilitate API development using compact code syntax and help you develop web APIs quickly. This practical guide explores Minimal APIs end-to-end and helps you take advantage of its features and benefits for your ASP.NET Core projects. The chapters in this book will help you speed up your development process by writing less code and maintaining fewer files using Minimal APIs. You’ll also learn how to enable Swagger for API documentation along with CORS and handle application errors. The book even promotes ideas to structure your code in a better way using the dependency injection library in .NET. Finally, you'll learn about performance and benchmarking improvements for your apps. By the end of this book, you’ll be able to fully leverage new features in .NET 6 for API development and explore how Minimal APIs are an evolution over classical web API development in ASP.NET Core.

Exploring logging in .NET

ASP.NET Core templates create a WebApplicationBuilder and a WebApplication, which provide a simplified way to configure and run web applications without a startup class.

As mentioned previously, with .NET 6, the Startup.cs file is eliminated in favor of the existing Program.cs file. All startup configurations are placed in this file, and in the case of minimal APIs, endpoint implementations are also placed.

What we have just described is the starting point of every .NET application and its various configurations.

Logging into an application means tracking the evidence in different points of the code to check whether it is running as expected. The purpose of logging is to track over time all the conditions that led to an unexpected result or event in the application. Logging in an application can be useful both during development and while the application is in production.

However, for logging, as many as four providers are added for tracking application...
